i get these very painful bruises, often on the balls of my feet... sometimes on the side/bottom of the heel, and occasionally on the arch of my foot. they don't seem to correlate to any pair of shoes or even any certain type of shoes. it also does not seem to correlate to any particular activity. they seem to pop up out of nowhere, and last for a few days. i have a pretty painful one now that started on the ball of my right foot a couple days ago, and is now also on the arch of my foot somewhat. i also have foot cramping because of how i've had to walk to avoid limping from the one on the ball of my foot.
these bruises seem to appear in a matter of a few hours, and take several days or up to a week to go away. i've been getting them for years and i would absolutely LOVE to know how to make them go away...
any ideas on what this could be??
